Answer:

The correct statement is option a, that is, when an electron drops down from a high energy level to a lower one, light energy is emitted.

Explanation:

The energy is quantized that is every orbit exhibits a fixed energy value. When the absorption of heat takes place by the atom, the electrons go from low energy level to the high level of energy. However, when energy or heat is discharged by the atom then the electrons travel from the level of high energy to the level of low energy. As a consequence, this heat is discharged in the form of visible light. Therefore, of the given statements, the accurate statement is that when an electron drops down from a high energy level to a lower energy level, the emission of light takes place.

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl
NikAS [45]

Answer:

Structures are given below.

Explanation:

  • Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
  • H atoms adjacent to Br will be eliminated.
  • 2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
  • Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
  • Structure of alkenes are given below.
